CHURN.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed July 14, 1905. Serial No. 269,679.

To all LUhO'IIL it Duty concern:

Be it known that I, ANDREW A. SEAT, a citizen of the United States, residing at Eldorado, in the county of Saline and State of Illinois, have invented new and useful Improvements in Churns, of whichthe following is a specification.

The invention relates to an improvement in churns, and particularly to mechanism for imparting a reciprocating motion to the churndasher.

The main object of the present invention is the provision in connection with the dasher of reciprocating mechanism and means for removably clamping the dasher-rod to said operating mechanism, whereby the churn may be conveniently removed from the operating mechanism when desired.

The preferred embodiment of construction of my improved churn will be described in detail in the following specification, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a churn constructed in accordance with my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is an end elevation of the churn. Fig. 4 is an enlarged sectional detail of the clamping means for the dasher-rod, and Fig. 5 is a broken side elevation of the same. Fig. 6 is a view in elevation of a tool for opening the dasher-rod clamp.

Referring to the drawings, wherein like parts are designated by similar referencenumerals throughout the several views, my improved churn comprises a suitable framework including a base 1, sides 2, ends 3, and top '4, the whole preferably forming a suitable inclosure for the churn-body 5, one of the sides or ends being hinged to facilitate introduction or removal of the churn-bucket. One of the sides 2 is extended above the top 4, preferably in skeleton form, to provide a support or a bearing 6. A second bearing 7 is mounted in alinement with the bearing 6 transverse the churn-frame, being supported in the same horizontal plane with said bearing 6 by a support 8, rising from the churntop 4, as clearly shown in Fig. 3. A powerweight 9 is fixedly supported on the inner end of a shaft 10, mounted in bearings 6 and 7, the opposite end of the shaft having the usual crank-handle. The power-weight comprises an arm 11, having weighted ends 12, said arm being centrally secured to the shaft and formed with a longitudinally-arranged slot 13 at one side of its connection with the shaft. A pivot-pin 14 is adjustably mounted in the slot 13 of the weight 9, projecting laterally therefrom and supporting links 15, pivotally mounted on said pin and maintained to space apart a requisite distance by a spacing-sleeve 16, encircling the pin between the links, as clearly shown in the drawings.

It is essential in connection with devices of this character that means be provided for the ready removal of the churn as a whole from connection with the operating parts to permit convenient assembling or disconnection when essential. To provide for this object, I have constructed a particular clamping means, clearly illustrated in Fig. 2 and designed to removably engage the dasher-rod of the churn. The clamping means comprises a frame 17, preferably of metallic spring-strips, having side arms 18 joined by a cross-arm 19 and with a cord-arm 20 in rear of the crossarm. At the forward end of the clamp the side arms 18 are joined by end arms 21 of comparatively short length and joining clamping-arms 22, which extend within and rearwardly of the clamping-frame, being connected at their rear ends by a partially-annular clamping -ring 23. The clamping-arms 22 extend from the arms 21 on an incline toward the clamping-ring, said arms 22 inclining toward each other in the direction of their length to provide a convergent passage leading from the forward end of the clamp-frame and terminating in the clamping-ring, all as clearly illustrated in Fig. 2. The space between the side arms 18 and the clampingarms and clampingring is preferably arranged to contain a suitable filler, as wooden blocks 24. The clamping-frame described is preferably of a single piece of spring material arranged to be sufiiciently yielding to permit the clamping-arms 22 to be pressed apart by the insertion of the dasher-rod 25 to exert a clamping pressure upon said rod when it is to be inserted within the clamping-ring 23.

The lower end of each of the links 15 is provided with a laterally-extending looselymounted pin 26, designed to engage the clamping-frame by passage through the side arm 18, through the wood filler 24, and seat in a suitable depression in the clamping-ring 23, as clearly shown in Fig. 4. By preference the openings for the pins 26 in the side arms 18 of the clamping-frame are elongated, as at 27, Fig. 5, to provide any necessary movement of said arms in securing the dasher-rod in place.

In use, as is obvious, the dasher-rod may be inserted within the clamping-frame by suitable pressure and the power-shaft revolved through the crank-handle to impart movement to the dasher. \Vhen desired, the dasher and rod may be instantly and conveniently detached from the operating mechanism by a simple pull on the rod to release it from the clamping-frame.

It is obvious that the pin 14 may be adjusted longitudinally with relation to the powershaft, whereby to impart the desired extent of reciprocation to the dasher-rod. V The construction described is simple and provides for the ready connection or disconnection of the churn from the operating mechanism when desired and also for the adjustability of the reciprocating stroke.

It will be noted in connection with the structure described that by the use of my invention the ordinary hand-churn is readily adapted for connection with the operating mechanism, as the spring-clamp will engage the rod at any point along its length, and it is not necessary to provide a particular dasherrod in the use of the mechanism described.

To provide for convenient operation of the clamping means described, I use the tool illustrated in Fig. 6, comprising pivoted crossarms 28, having suitable handle ends and formed at the ends opposite the handle ends with right-angle projections 29, designed to be inserted between the clamping arms 22 and operated to force said arms apart to release the dasher-rod in an obvious manner.

Having thus described the invention, what is claimed as new 1s 1. The combination with a churn having a dasher-rod, of operating mechanism therefor, and a spring-clamp carried by the operating mechanism and designed to engage the dasherrod, said clamp comprising divergent clamping-arms connected with a partially-annular clamping-ring.

2. The combination with a churn having a dasher-rod, of operating mechanism therefor, and a spring-clamp carried by the operating mechanism and designed to engage the dasherrod, said clamp comprising side arms connected at one end by a cross-arm, divergent clamping-arms connected at one end to the side arms, and a partially-annular clampingring connected to said clamp-arms.

3. The combination with a churn having a dasher-rod, of operating mechanism therefor, and a spring-clamp carried by the operating mechanism and designed to engage the dasherrod, said clamp comprising a spring-frame of skeleton outline having side arms connected at one end with a cross arm, convergent clamping-arms projecting Within the frame and connected at their inner ends with a partially-annular clamping-ring, the outer ends of said clamping-arms being connected to the side arms and filling-blocks between the side arms and clamping-arms.

In testimony whereof I aifix my signature in presence of two Witnesses.

ANDREW A. SEAT.
